感谢任何建议

尝试安装当前版本的xamarin.forms.map:2.3.3.180

我今天遇到了同样的问题，它似乎与来自两个C#项目的两个不同的依赖关系有关，其中一个被另一个使用/引用。从我所看到的情况来看，可能安装了相同依赖项的两个不同版本。最有可能的是，您可能需要合并您的NuGet包。这可能是错误消息试图表达的意思。重复类型之一是Android.support.v4.view.iviewPropertyAnimatorListenerimplementor，它包含在xamarin.Android.support.v4和xamarin.Android.support.compat两个库中。至少对于我的解决方案来说，这是由于xamarin.android.support.v4 NuGet包的两个不同版本，即25.3.1和23.3.0版本。由于Xamarin.Forms NuGet包的依赖性，我必须显式地降级到23.3.0版本，这似乎解决了这个问题。
